标准回肠可消化赖氨酸与净能比对猪生产性能的影响

Effect of Standard Ileal Digestible Lysine to Net EnergyRatio on Performance of Pigs

目前猪饲粮配制主要基于净能(NE)系统,并根据标准回肠可消化赖氨酸(SID-Lys)来平衡其他氨基酸。饲粮中SID-Lys/NE过高或过低都将对猪的生产性能、经济收益及环境造成不利影响。因此,准确配制满足猪营养需要的SID-Lys/NE至关重要。本文就不同SID-Lys/NE对猪生产性能的影响进行综述,为合理优化配方提供参考。

At present,the energy system in the diet is mainly formulated based on net energy(NE),and other amino acids are balanced according to the standard ileal digestible lysine(SID-Lys).Too much or too little SID-Lys/NE in the diet has adverse effect on pig performance,economic profitability and environment.Therefore,it is important to accurately formulate SID-Lys/NE that meets the nutritional requirement of pigs.This article reviewed the effects of different SID-Lys/NE on pig performance and provide reference for reasonable optimization of formula.
